UNITED STATES JAMES CHARLES GARNER, OF HOUSTON, TEXAS.

corren GIN.

Application 'led June 3, 1925.

To all vwhom it may concern.'

Be it known that li, JAMES CHARLES GAR- Nnn, a citizen of the United States, residing at Houston, in thc county of Harris and State of Texas, have invented new and use-v larly useful for the purpose of separatingl lint cotton from the cotton seed and also for 'separating the bolls, stems, metes and other foreign matter from the lint; and for collecting said lint and foreign matter separately and discharging them separately from the gin.

Another object of the invention is to provide an improved form of driving mechanism which will enable the gin to be associated readily with other machines, and by means of which any machine in the battery may be thrown into and out of operation independently of the others.

A further object of the invention is to provide means whereby the air ducts and saws may be quickly cleaned; and to arrangethe air nozzle so that there will be no' tendency to accumulate metes adjacent the saws.

A still further object of the invention is to provide an improved main flue construction which permits each flue section to be supported by a .machine frame 'so as to reinforce the latter, and in which the flue sections are also adjustable in size without bodily moving, each section.

Other objects of the invention relate to the arrangements of the supply duct in each gin with reference to the main flue whereby the lint may be delivered into the flue in the direction paralleling the passage of material therein, thereby avoiding back pressure; to the arrangement of the main flue and Seed delivery mechanism within the frame so as to reinforce the machine frame,

and to the structure of Athe main deliver flue, which, preferably, is divided longitudinally to enable the sections of the same to be transversely adjusted in size.

The above and additional objects of the invention will become clear as the description proceeds in connection with the accom- Serial No. 34,667.

panying drawings, wherein the improvements are illustrated as embodied 1n any machine of the type disclosed in my Patent l 1,520,412, granted December 23, 1924, although it will be understood that these improvements are of generalapplication in the art and may be embodied. in numerous types of machines.

In the drawings:

Figure 1 is a front elevational view of a gin showing the means for connecting the same with another machine for use in a battery of gins Figure 2 is a vertical sectional view taken through a gin, i

Figure 3 the driving mechanism,

Figure 4 is atop plan view of the gin battery with parts broken `away, and

Figure 5 is a sectional view showing the inlet. of each delivery duct to the main flue and tak-en on substantially the line 5 5 of Figure 2.

Referring to the drawings for a more detailed description, 10 indicates the end plates of the supporting frame which have is a detail view of a portion of 4 disposed between them the operative mechanism of the gin. Pivotally mounted in bearings 11, disposed at the upper edge of these plates, are pivot pins or trunnions 12, which carry side plates 13 at the front of the gin and between and carried by the latter is positioned the wall 14 forming the gin breast. The usual picker wheels 15, 16 are mounted upon shafts 17 carried by the plates 13 and serve to present cotton introduced behind the wall 14 to the saws 18 mounted upon the saw shaft19 carried by the frame end plates 10. spaced uniform distance apart upon the shaft 19, and are suitably 'serrated so as to engage with the lint and Strip the same from the seed. l5 are arranged the huller ribs 20 with their lower ends secured to the transverse bar 21 fixed to the plates 13, and their upper ends to the transverse bar 22, both of these bars serving to connect the plates 13. The huller ribs are arranged to alternate with the saws and are spaced a sutcient distance apart to permit the lint and seeds to pass between them when carried by the saws, but they arrest all .bolls, stems, leaves and other foieign matter which may be in the cotton and prevent the passage of this foreign matter into the roll box 23, which will la- These saws are i Behind the picker rollers ter be described. The seed cotton passes down behind the breast 14, and is engaged by the spikes of the picker rpllers, which carry them into engagement with the saws; the latter carry' the seed cotton through the huller ribs 2O into the roll box, but the foreign matter is arrested by the ribs and drops down upon the picker roller 16, by vwhich it is discharged upon the detlectlng plate or valve 24 and on to the conveyor 25 beneath the machine. I

Spaced behind the huller ribs 20 are the stripper ribs 26, having their lower ends secured to the transverse bar 27 and their up` per ends to the transverse bar 2.8, these two bars being secured to and serving to space the plates 13. The stripper ribs are arranged alternately with` respect to the saws and are closely placed to prevent the passage of seed between them, but they permit the saws lto carry between them lint cotton, motes, and other small particles. l noted that the upper ends of these ribs are curved to form the back or rear side 23 of the roll box 23, which is smooth and free of lint engaging projections. The. opposite side of the roll box is formed by the roll box breast 29, which is arcuate in cross section.

The roll box breast 29 and the opposing ends of the stripper ribs 26 are oppositely curved so as to form between them a substantially cylindrical roll box with smooth interior walls, in which the seed cotton collects in a mass, and throu h which the saws 18 pass as they rotate. pposed to the breast 29 1s an'imperforate rear wall 29 to complete the substantially cylindrical structure of the roll box.

The saws pass through theA cotton in the roll box and engage with the lint therein, causing the mass of cotton in the box to rotate constantly and thereby coming repeatedly into contact with the saws which strip the lint and motes from the seed, the lint being carried by the saws between the stripper ribs 26. The seed is arrested vby the ribs vand 'when free from the lint, gradually works from the roll and drops onto-the retaining-board 30, which: is secured to the.

transverse shaft 3l. ,rotatably mounted in suitable bearings in the end plates 13. The free edge of the board is slotted forming lingers 31 which are uniformly spaced apart and project'between the saws 18. When the board 30 is in the position shown in Figure 2, it will deflect the seed Aand other foreign matter downwardly between the huller ribs 20 and stripper ribs 26 to the trough 32,

ywhich is formed of relatively stiff metal and is positioned in openings 33 formed in the frame end plates 10.

` Above the trough may be positioned a del,fleeting plate 34 pivoted at 35 and serving to direct'seeds to the trough 32, in which is positioned va conveyor shaft 36 carrying a It will bef spiralconveyor37, adapted to direct the seeds longitudinally of the trough to any suitable point of deposit. Ordinarily, the seed conveyor 37 is positioned beneath the gin at substantially the location of the boll and leaf conveyor 25but by arranging the same in the position indicated, the trough 32 serves to reinforce the frame and to provide a "more self-contained gin. The board 34 may be arranged in the vertical position indicated in full lines in Figure 2, which directs seed from the roll box 23 to the conveyor 37, or, when desirable, it may be carried to either of the positions indica-ted in dotted lines against stops 34 or 34, and either direct the discharged seeds and other material downwardly into the board 24 and von to the conveyor 25 beneath the machine,

structure is formed by a top wali 40 extended upwardly to a relatively narrow or knife edge 4l, and then downwardlyA and laterally to form a nozzle opening 42, which extends the entirel width of the saws within the machine and serves to discharge an air blast substantially tangentially with respect to the saws in order tov doff the lint from the latter and direct the same into a duct 43, which leads to the main lint flue 44, as will be later described in detail. The .nozzle passage 42 is between'the downward'and Vlateral extension 41 of the wall 40 and the i upper end of anapron or air board 45, which is positioned over the sawsfor substantially the entire width of the same in the machine,

vand overlaps, at its lower edge, the wall 43 of duct 43. The lairboard 45 contines the blast issuing from the nozzle 42, and thereby directs the dotl'ed lint into the duct 43. As indicated in dotted lines, both the nozzlel and air board 45 are movable with the Hue 39 when the latter is swung pivotally away from the saws. It is broadly old to mount the blast nozzle and air blast duct for pivotal movementtoward and from the saws, -and such a structure is shown and claimed in the patent above referred to. The present construction, however, is an improvement upon the patent, in that the air board or apron, which extends from the saws, is likewise movable toward and from the saws, and movement is imparted to the same by actuation of the nozzle. In other words, the air board is movable with the nozzle, land hence may be readily cleaned, together with the nozzle. This isliighly important, since the effective-ness ofthe blast depends upon a -clearand unobstructed passage -from the nozzle 42 tothe duct 43.

It should also be noted that the wall 40 of the duct forms a relatively narrow or knife edge 4l above the nozzle, instead of being rounded to provide a comparatively wide f f surface for the accumulation of motes, which tend to form a body labove thenozzle and to obstruct the operation ofthe saws when a. supporting surface is4 present. TheA motes. are directed to the rear of the wall 40 along a rearwardly and downwardly inclined passage 46 to the trough 47 carried by the iaine, and in which is positioned a mote conveyor 48. A shutter or closure 49 is pivotally connected at 50 to a transverse bar 5l,

and at its upper end, when closed, rests u on i 20 a shoulder 52 formed `upon a transverse ar 53. This shutter, together with the wall 440 of the duct and. downwardly .extending wall 40', serves to form the'inote passage 46 lead. ing tothe mote conveyor 48.

vReferring again-to the duct 43, .through which the lint is led from the saws to the 'main flue 44, it will be observed that this duct-has an inner wall 54, -which is extended upwardly adjacent the saws and then. forwardly and downwardly to a transverse se.

curing. strip 55. To this st rip is also secured the upper end of a partition 56, which,

at its lower edge 57,'is joined, to the seed trough 32 to form a relatively closed .passage for the seeds leading from the roll box 23 to the trough 32.

I The walls 43', Y54 of the duct 43 are prefj. I, erably formed integral withA the walls 44 of -lthe main flue. The back wall 59 (Figures 40 2 and 5) of the duct projects into the main flue and curves forwardly, so -asto direct the lint entering the flue in a direction parl alleling the passage of material in the latter,

and, preferably, the inlet duct should open into' the main Hue only at its forward end.

` For this purpose, a'.A partition 60 (Figures 2 1 and 4) is positioned in the niain flue and exf-tends forwardly and also somewhat trans- Aversely within the main flue to provide an outlet portion' for the duct 43 which broad ens or increases in area as it extends for- .wardly in the main flue.` At the forward end of the. partition 60there is formed an 4 outlet opening 61,`through which the lint emerges in a direction substantially paralleling the line of travel of the materialin the main .Hue 44, and thus there is prevented the formation of eddies at the outlet opening `6l and back pressurein the duct 43.

fReferrin to the construction of the main lue 44, an more particularly to Figures 2 and 4, it will bel observedthat the various portions or sections of the same are mounted in substantially U-shaped horizontally disposed seats in the machineframe. The va- .rions sections may be `'joined between the machines Aby connecting sections 62, which overlap the ends'of the main gin section,

along lines 62" in the usual manner, and, :preferably, the section in each machine is divided longitudinally alongy a line 63 Ifor the purpose of` permitting an increase cr .decrease in the cross` sectional area of each section and to accommodate the capacity of each sectionv to its positionin a battery of gins. As will be understood, the rearmost gin A need not have associated therewith a, flue section having a capacity as large as onev of the forward gins B, C or D, and, preferably, tlie capacity of the main flue should increase in the direction'ofvthe outlet end 64, since each of the gins A, B, "C and D are emptying into the main flue.

Obviously, there are. various suitable mechanical expedients ormaking` possible variation inthe size of each flue section.' As' stated, the preferable means is to divide the .section longitudinally alongl tlie'li'ne 63, vthereby forming each flue'sction into two `longitudinalsubsections, which are an innerA sub-section 64 and .anLouter 'sub-section. 65. The two subfsections' 'ma be united Ain any .suitable manner, as 'by endingv outwardly the meeting edgesy 6 6 'and clampingthesame together. The inner secti-onl64 iscarried in ya horizontally disposed U-sliaped seat 68, in

by-securing bolts 71, and clip the juxtaposed upturned edges 66 'offthe Sub-sections inl vfixed position.

.By referring to Figure it will be oh'` served that although the inner sub-sectionsof the main flue throughout its entire length division line' 63 between the sub-sections, the outer subsections increase 1n widthfforwardly of the flue so as to providejamain 'are of uniform width, as indicatedbythe flue of gradually increasing vdiameter to take care of the lint which increases in.

volume as it travels forwardly" in the flue. It will be observed that by' the ,construction illustrated and described, the diameter of the iue .section associated witli any gin -may be varied as desired, and int ispossible to insert a gin in a battery in anv pre.

ferred location and' to associate 'with it a main flue section of the necessary capacity without removing the entire flue section.

In other wm'ds,1the-` inner sub-section (it which accompanies each gin and is integral with theinlet duct 59 is of the same size in'eachgimand variation in the main flue. capacit-y is vobtained by varying the sizeof will be\ observed that vthe connecting'sections (32 are also divided longitudinally, andthe edgesl of the sections are turned out wardly to form flanges through which se- Atthe rear end of' the main flue 'and near the last gin A of the battery is provided an air inlet opening 75, .with which may be con' nected a 'draft piper-76 v(Figure 4) for the 'purpose of admitting the desired'amount of air to the end of the flue. lThis is desirable, since, if the flue is closed there will be .formed vand cause what is commonlylrnown as gin fault. Thislow'ers the value ot the'cotton,

and, of course, .hould be avoided. The opem i *standing arms 88 (Figure 3) upon the end ing 7 5 enables the supplyfol s'uicie'nt air to the main flueto overcome back pressure when the flue is used yin, con'nectioirwith an air blast and also serves to 'admit a cer-V v tain 'amount of air when the flue is used in connection with a vacuum condenser.

A further important feature of theinvention relates to the means for driving-each gin and for associating the saine with other gms of a battery. This mechanism will nowV be described. i c

Ordinarily, power is transmitted to machines of this typefrom a 'main .drive shaft paralleling the gin or battery fv .vins and connected by belts with suitable pnl on one of the gin shafts, the latterbeing '1nterconnected for Vdriving the various conveyors and other moving parts. Not int'reqnently such arrangements, particularly when driving belts areemployed, are the cause of fires and the complete destruction cf gins and entire and ignition. The presentvinvention contemplates the elimination -of all driving4 belts, as well as independent power shafts, and it is proposed to house .or completely enclose the drivingconnections which may be gears, or, preferably, silent chains.

. illustrative of the invention, there is mounted in the end plates10 of each frame a main drive shaft 'section 7 9, which is arranged .between the walls 54 and 5G and below the the latter. The shaft section is mounted in suitable bearings 80 (Figure 1), and at least one end -of the same is extended'beyond the machine so that it may be coupled, as by means' of a compression coupling 81', with the main drive shaft section of an adjacent gin. Each drive shaft section is preferably connected independently with the saw shaft a dead end, causing the accumulation of lint and dust, which will finally break' leys up;

19 by driving connections which may be optionally rendered operative or inoperative, whereby the saws o'l' one or more of the gins of a battery may be stopped without disturbing the operation of the other gins.

the outer sub-sectionG, as described. j lt This 'driving means is of a character which permits the saws to bereadily reversed either by reversing the mam shaft, or, if desirable,

` the connections maybe of a character which enables the saws of any gin 'to be reversed without reversing ythe main drive shaft.

fto move the collar longitudinally of the shaft and vthereby force the driving member 82 into frictional engagement with the driving clutch member 85, the latter having a sleeve portion 86 extended into a housing 87. The housing 87 is supported by means of outby means of a tightener sprocket 92 mounted Ein a slidable block 93. "adjusted by' ay screw The block 93 is 94, which extends through -an'opening 95 in the housing and threadedv into the box. By means of' the clutch, the sawlsliaft of any gin in a battery may be stopped and started as desired, and the chain drive being comparatively silent and entirely housed 1s not only positive in action, but will not tend to cause ignition of the lint. Obviously, gearing or other drive mechanism might be substituted for a c hain drive andwonld be equally efficient. Due to the division of the main d rive shaft into sections each carried by a gm, stalled in a battery and forms a complete self-contained unit. Power may be applied tothe shaft at any suitable point, either at one end of the unit orbetween intermediate 'gins. l
